IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. 222,929, dated December23, 1879} application filed August 2, 1879.

To all whom it may concern:

Be it known that I, WILLIAM P. MILLER, of Tipton, in the county ofMoniteau and State of Missouri, have invented a new and ImprovedNut-Lock, of which the following is a specification.

Figure 1 is a perspective view of the device as applied to a rail. Fig.2 is a cross-section of the same on line as as, Fig. 1. Fig. 3 isadetail hereinafter referred'to.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a cheap, simple, eifective,and easily-adjusted nut-lock.

It will be seen that each slot in the lock-plate embraces twonuts instead of one, as is commonly the case, and it is found that thisarrangement makes the plate more easy of adjustment and of less weightand cost.

The arched notch 01, cut in the lower edge of the plate, is toaccommodate the head of the spike that assists in holding the rails tothe sleeper.

It is obvious that in the ease with which this look can be applied orremoved, in dura-
